Description

BCRSMatrix does not initialize the memory allocated for the actual matrix values when the matrix is created using the random scheme. While this is unproblematic in the common case where the block type is some kind of FieldMatrix, this behavior causes crashes if the block type is again a BCRSMatrix, since the BCRSMatrix has a non-trivial constructor.

Is this behavior desired (to speed up matrix creation)? If not, the attached patch fixes the issue for me.
